How to Turn Any URL into Clean Markdown for AI Agents & Run Instant SEO Audits (WebPulse API)

If you are building AI agents, RAG (Retrieval-Augmented Generation) pipelines, or automated scraping workflows, you already know the painful truth: raw web HTML is an absolute token burner.

Feeding a full raw webpage into GPT-4, Claude, or Gemini wastes up to 80% of your context window on navigation bars, cookie banners, tracking scripts, and inline SVGs.

To solve this, I built WebPulse AI & SEO Suite API: a lightweight, ultra-fast 5-in-1 web extraction API that converts noisy URLs into clean, token-optimized Markdown, extracts rich metadata, audits technical SEO, and discovers B2B contact info in milliseconds.

Here is how it works and how you can test it for free today.

⚡ 1. The Core Problem: LLM Token Bloat

When you fetch a typical blog post or documentation page:

• Raw HTML size: ~250 KB (approx. 60,000 tokens)
• Actual readable content: ~15 KB (approx. 3,500 tokens)

Sending raw HTML to your LLM costs real money, slows down responses, and degrades reasoning accuracy.

With the /api/v1/markdown endpoint, WebPulse strips away all boilerplate and returns:

1. Pure GitHub-flavored Markdown.
2. Formatted plain text.
3. Pre-split semantic rag_chunks ready to embed into vector databases (Pinecone, Chroma, Supabase).
4. An automated calculation of your exact token savings percentage (llm_token_savings_percent).

Quick Python Example:

import requests

url = "https://webpulse-ai-markdown-seo-audit-and-contacts.p.rapidapi.com/api/v1/markdown"
querystring = {"url": "https://stripe.com"}

headers = {
"x-rapidapi-key": "YOUR_RAPIDAPI_KEY",
"x-rapidapi-host": "webpulse-ai-markdown-seo-audit-and-contacts.p.rapidapi.com"
}

response = requests.get(url, headers=headers, params=querystring)
data = response.json()

print(f"Token savings: {data['data']['llm_token_savings_percent']}%")
print(f"Clean Markdown sample:\n{data['data']['markdown'][:300]}...")

🔍 2. Instant 25-Point Technical SEO Audit

Most SEO tools are heavy, expensive, or require full browser emulation.

The /api/v1/seo-audit endpoint runs a 25-checkpoint audit directly at the HTTP and DOM level in under 150ms:

• SEO Score (0–100) & Grade (A+ to F)
• Meta title, description, and canonical tag validation
• Heading structure hierarchy (H1 to H6 check)
• Missing image alt attributes count
• Internal vs external link balance
• Security & indexability verification (robots, HTTPS)
• Structured lists of critical_issues, warnings, and passed_checks

Perfect for agencies offering automated client onboarding reports or developers building automated website monitors.

💼 3. B2B Contact & Social Profile Discovery

Need to enrich company profiles automatically?

The /api/v1/contacts endpoint crawls the target page and detects:

• Corporate & support emails (categorized by role vs direct address)
• Phone numbers
• 10 major social networks: LinkedIn, X (Twitter), GitHub, YouTube, Instagram, Facebook, TikTok, Discord, Telegram, WhatsApp
• Key corporate pages: Pricing, Contact Us, About, Privacy Policy
